Pump energy-saving air conditioning unit with double power sources and control method thereof

Abstract

The invention discloses a pump energy-saving air conditioning unit with double power sources and belongs to an air conditioning refrigerating unit, and the unit provided by the invention is mainly used for solving the problem of poor refrigerating effect of the compressor refrigerating unit under the low-temperature environment in the prior art. The fluorine pump energy-saving air conditioning unit with double power sources comprises a compressor refrigerating unit mainly consisting of a compressor, a condenser, a liquid accumulator, a dry filter, an evaporator and a gas-liquid separator, wherein the compressor, the condenser, the liquid accumulator, the dry filter, the evaporator and the gas-liquid separator are successively connected via a transmission pipeline; the gas-liquid separatoris back connected with the compressor; and in addition, and the fluorine pump energy-saving air conditioning unit with the double power sources is also provided with a fluorine pump refrigerating unit connected with the transmission pipeline between the liquid accumulator and the dry filter in parallel. The invention also discloses a control method of the energy-saving air conditioning unit, and is mutually matched with the energy-saving air conditioning unit to freely switch two refrigerating units; the refrigeration effect of the fluorine pump conditioning unit under the low-temperature environment is greatly improved by the fluorine pump conditioning unit; and the cost is saved.

Description

technical field [0001] The invention relates to an energy-saving air-conditioning system, in particular to an energy-saving air-conditioning unit with dual power source pumps and a control method thereof. Background technique [0002] With the development of society and the acceleration of industrialization, the lack of resources and the deterioration of the environment have become urgent problems for human beings. In recent years, all countries in the world have put forward the slogan of "protecting the environment and saving energy". my country also vigorously advocates energy saving and emission reduction , as a large energy consumer, air conditioners have naturally become the focus of attention in all industries, and the development of environmentally friendly and energy-efficient air conditioners has become the goal pursued tirelessly by every air conditioner company. [0003] At present, the most commonly used energy-saving air conditioners use compressor refrigeration ...
